10 Claims.

My invention relates to a scoreboard for tallying the scores of bowling games, and eliminating necessity for personal supervision to prevent fraud in paying for games bowled; and involves coincontrolled means for selectively and controllably moving a shiftable tally sheet to exposeispace to receive the scores, and an important object of my invention is to provide a simple, efficient, and practical arrangement of this character.

Another important object of my invention is to provide in an arrangement of the character indicated above, electrical signaling means in connection with the operating mechanism whereby the pin boys working on the bowling alleys to which the scoreboard relates, can be informed of the number of players about to begin; a game, the number of players being so designated by selective operation of the scoreboard to uncover and expose a corresponding number of score spaces, depending upon the number of coins deposited in the coin controlled mechanism Another important object of my invention ,is to provide in an arrangement of the character indicated above, means enabling adjusting the scoreboard rotatably on a vertical axis, andtransversely in a horizontal plane, relative to its base. Another important object of my invention is to provide coin controlled operating mechanism for the selective feeding of the tally sheet, whereby overfeeding and underfeeding of the tally sheet is positively prevented, and fraudulent oper-'- 'ation of the scoreboard eliminated. 7

Other important objects and advantages of my invention will be apparent from a reading of the following description taken in connection with the drawings, wherein for purposes of illustration I have shown a preferred embodiment of my invention.

Figure 16 is anelevational view of one of the roll cores showing the reduced projections on the opposite ends thereof, one of these being squared.

Figure 1'? is an elevational view of the 'back of the scoreboard casing showing the adjustable hingeblamp bracket connecting the supporting pedestal thereto. v j Referring in detail to the drawings, the numeral 5 generally designates a transversely elongated generally rectangular casing which-has semicylindrical-hollow projections 6 and 1 at its upper and lower ends which extend across the back thereof. Horizontally hinged as indicated by the numeral 8 to the lower edge of the portionl is the lower closure9 which has an inturned portion I0 terminating in a vertical flange; l-l against whichfit the vertical flanges I2 on the lower ends of-swingable side closures; l3 M which are vertically hinged as v indicated by the respective numerals l5; l6-to the front edges of the side walls of the casing intermediate the top and bottom of the casing, so that; .the member 9 is held in closed position when the side -members I3 and M are in closed position. Holding the side members in closed position is the downwardly swingable upper closure member I l which is hinged to the upper edge of the portioni as indicated by the numeral [8 and has an inturned lip IS on its lower end which bears against the outer side of v the upper; part ofthe side members l3 and I4.

A look IT has a bolt 18 to=lockably engage a detent IS on the member ll.

Horizontal I beam formations 20, 2| and 22 are secured to the back of .the casing and extend across the casing to act as supports for the table v the rollers 32' and 46 and is taken on the lower receiving roller 41 which is mounted on a core '48 having its ends removably journaled in appropriate brackets 49 and 50 mounted in the lower -semi-cylindrical section 1 of the casing all as shown in Figures 2 and 3 of'the drawings.

The cores '26 and 48 are made removable to .enable' inserting a new roll of, paper at the top,

of the casing when the roll in place is-exhausted and all wound onto the lower core. The wound lower core i removed and replaced by the empty upper core. The free end of the new roll on the upper core is brought down and clipped to the lower empty core.

23 which has clips 24 at its side edges to engage around theedges of the paper tally sheet 25 as indicated in Figure 4, so as to maintain the'paper' tallysheet in writing position relative'to' the table 2 3, as the paper is moved along relative to the table 23' and halted in place to be written upon by the scorekeeper.

upper papershe'et roll core 26 is removably I journaled in-respective brackets 21 and 28 which are secured to the back of the casing, the said core being' in substantial concentric relation to the semi-circular portion 6 and engaged at one end with'ia ratchetwheel 2'9, rotatably fixed to v the bracket '28, with which constantly engages a ratchet pawl 3i] which is pivoted on the side wall of the casing and has a spring 3! pressing the sameinto'engagement with the ratchet wheel,

all,as -illustratedin Figures 2 and 3, The supply of tally sheet paper is wound on the core 26 so as to feed off the frontthereof and downwardly as indicated in Figure 3 infront of the table 23,

first Passing between the idlerroller 3 2 and the paper feedingroller 3 3. .I -S P bracket 34 mounted on the back of the'casing just below the semi c'ylindrical portion 6 carries the rotary shaft 35 which-extends across the casingtoa similar bracket'and thisshaitg'35 has on the right hand end thereof the sprocket '36 'over whichythe sprocketchainSl is trained. The standard pon tionf lg of, the bracket 34 has; pivoted thereto "as As shown in Figure 7 of the drawings the shaft 48 has thereon a pulley 5! over which is trained a belt 52 whichis also trained over a pulley 53 fixed on the shaft 26'. This belt 52 is loosely trained over these pulleys so as to afford a certain amount of slippage when the amount of paper rolled on the core 48'soincre'ases the-diameter of the roller as to otherwisecause unwanted faster and larger feeding of the paper by the turning of the manually operated knob' after the coin controlled mechanism has been operated, for'the purpose of exposing an'appropriate number of spaces to receive the scoresof players about to begin a game; thereby allowing the parts to work in such a manner as to retain the same relative amount of feeding of the paper as obtains when the receiving roll 41 has only a 'moderate amount'of paper wound thereon. The

core has a squared end which connectibly enters a'sim'ilar opening in the pulley 5|, in a manner similar toth'e connection of the upper core with the ratchet wheel 29, the opposite ends of these cores turning freely in the'brackets provided.

5 The operating knob '54 which is exposed at the right hand side of the casin'g' as indicatedin indicated by the nun eral 38 the arm 39"torone endeof which-is journaled the shaft 40 which carries: the idlerroller-QZ which extends across the casing and engages the exposed faceof the tally sheet 25 and presses the tally sheet' into frictional engagement with the feeding ,roller f33 byvirtueof: the"presence'of the'spring 42 which is stretched between thel freelend of the arm 39 and a portion 43 off-thestandard portion 44 of the bracket 34, allas shown in Figure 6 of, the

drawings. A substantially: similar arrangement at theopposite end of'the idler rollerfrom' that shown infFig'ure ,dobtains at the Opposite side of jthle .casing;

7' The lower yendyofqthe sprocket chain 31 trained' over asprocket 45 which isjsimilar "to the sprocket 35 and like the sprocket 56 is -located on; a 'shaft'zt' simil'a'rfto the shaft 35 and similarlyr'nountedfat both endsto the backfof the e s b m ns O ;;b t$1 im to the brackets 34,-jwhereby the :two feeding rollers 33 and 46, are operativelyconnected together. An

Figure 2 of the. drawings'is mounted'on' an extension of the shaft '26" w hich has the pulley 53 thereom so that when the coin controlledmech- 'a'nism has been properly operated to the released position, turning of the knob 54 in" the paper feeding direction will coordinately rotate the frictionalfeeding rollers 46 and'33, and thereby v feed the paper downwardly from the supply roll to' thereceiving roll 41. The arrangement is such that each :time a coin of the. proper deidlerpressing'roller; SZQfsimiIar in all respects to ftheflpressing roller '32 already described is disposed relative-to thefeeding'roller 4.6, and asup port of the 'presser roller 32' is similar in all respects "to that describedin' connection with the idler;pressurejroller--32- except that the arf .i nsem nt 'S Q aiaFi fiiS ed! 3 The paper tally sheet-25 feeds down' b'eyon'd nomination is utilized in the coin controlled mechanism and the coin controlled'mechanism operated, the. knob'54 can be turned only a certain distance, namely one-half revolution, so'that no, more and no less than one fullscore space 55 onthe paper 25 i brought into view below material element 58 whose opposite ends are exposed through the insulating material 51. for engagement by the spring-pressed contact 59 which is mounted in abushing GOsecured on an insulated bracket 6|, projecting from the adjacent'slde'wall of the casingas shownin Figure .2,

' the contact member 58 being grounded 'as' indicated'by the numeral 132 while a 'wire'63' leads fromthebushing 60 to a warning device such as a lamp on the pin setting machine or in the alley pit, whereby the pin boy or boys are given immediate notice automatically upon bringing the desired number of scoring spaces into view, that a corresponding number of persons is about to bowl. The tally light is operated by the coin operation of the device once for each coin deposit so as to enable the pin boy called to check on the number of persons who have paid to bowl on his alley. To call the pin boy from the pin boys lounge, the call spotter button I49 is pushed thereby sounding a call and indicating the num-- ber of the alley calling. The call manager button I50 is only used in an emergency, as when the pin boy fails to duly appear after operation of the call spotter button.

Thecoin controlled mechanism and associated mechanism is located at the right hand side of the casing and mounted on the back of the easing as well as on the support members 2| and 22 and the longitudinally operating parts work in vertical planes and in a vertical position as clearly shown in Figure 2 of the drawings. The arrangement and operation and construction of this mechanism is shown in Figures 8, 9 and 10 wherein it is shown that on the extension of the shaft 26 on which the knob 54 is fastened is secured the ratchet wheel 64 alongside of the secondary locking disk 65. at diametrically opposite points with radial slots 66 and 61 designed to receive the end of the locking rod 68 which is slidably mounted in a bracket 69. To the right of the disk 65 is the primary locking disk I which is fixed to the shaft 26 with its diametrically opposed peripheral radial slots II and I2 spaced at 90 of rotation from the slots of the disk 65 and arranged to be engaged at certain stages of operation by the dog I3 on the end of the pawl I4 which is pivoted as indicated by the numeral I on the bracket I6 and has a clevis 'I I on its end opposite the dog I3 in which is pivoted as indicated by the numeral I8 one end of the connecting rod I9. In addition there projects from the right hand side of the disk I0 diametrically opposed lateral fingers 80, 8| which are adapted in the rotation of the primary disk'lll in the direction indicated by the arrow to alternately engage the tiltable releasing rod 82 which is pivoted intermediate its ends as indicatedby the numeral 83 on the supporting bracket 84. A ratchet pawl 85 is pivoted as indicated by the numeral 86 on a bracket support 81 and pulled into engagement with the ratchet 64 by a suitably arranged spring 88.

The upper and clevis equipped end 89 of the connecting rod I9 is connected as indicated in Figure 9 to the lower end of the locking slide which is generally designated 90 and which is mounted in slide brackets 9| and 92 and has attached to its upper end a retracting spring 93 which is stretched between the said upper end and a stationary bracket 94. The upper end of the 'rod 82 is pivoted as indicated by the numeral 95 to the upper end of the L-shaped arm 99 which is secured as indicated by the numeral 91 to the lower end of the latch bolt 98 which is vertically slidably mounted in the support 99 which encloses an expanding spring I00, the support 99 being secured to the backof the casing in a position under the laterally enlarged portion IOI of the locking shait'90 as indicated in Figures 9 and ofthe drawings: The enlarged portion IOI has a longitudinally elongated slot I02 into which The disk 65 is provided the latch 98 is adapted to project as indicated in Figure 9 of the drawings in a certain position of operation of the parts. A stop I03 adjacent the upper end of the slot I02 is also adapted to be engaged by the latch 98 in another position of the parts for the purpose of holding the shaft 90 in a downward position against the tension of the spring 93. The upper end of the shaft 90 has another stop I04 on the back thereof the function of which will be described herein.

The upper end of the primary locking shaft 68 passes through a slide bracket I05 and pivotally connects as indicated by the numeral I06 with a clevis IN on a connecting rod I08 which has a clevis I09 on its upper end pivoted as indicated by the numeral IIO to an intermediate portion of the coin slide operated lever II I which is supportably pivoted as indicated by the numeral II2 on a projection II3 on the side' of the coin slide casing 4. A retracting spring H5 is stretched between the point H6 on the lever III and a bracket II'I'fastened to the upper part of the coin slide casing, all as shown in Figure 9 of the drawings. The inner end II8 of the lever III extends within the coin slide casing II4 for operative engagement by the coin slide I I9 when the coin slide is pushed upwardly in operating the same after insertion of a proper coin in the receiver I20, the coin slide casing being mounted on the outer side of the right hand side wall of the scoreboard casing 5 as illustrated in Figure 1 of the drawings.

When the prospective bowler inserts proper coins in the slots and presses coin slide I I9 ahead. the free endof the lever III is caused to bear against the stop I04 on the locking slide 90, and pushes this slide in a left hand direction, to constitute an activity called cocking. As the looking slide 90 moves in the direction stated, the stop I03, attached thereto, bears against the inclined face of the latch 90, and causes the latch to be depressed within its support 99 and against the tension of its expanding spring I00. When the slide 90 is pushed in the left hand direction such distance as to cause the stop I03 to have completely passed over the latch 98, the latch arises, thru its expanding spring I00, to a position behind the stop I03, and, thereby, to fix the locking slide 90 in this cocked position, all of which is apparent in Figure 10.

Simultaneous with this activity, the action of slide 90 works the connecting rod I9 so as to withdraw. pawl I4 from the notch II of the primary locking disc I0. Now the disc I0 is free to be turned in the direction indicated by the operating knob 54which is connected with this disc by the continuous shaft 26'. Immediately or very soon after the turning of the operating knob 54 is begun, the lateral finger 8| on the disc I0 will strike the adjacent end of the latch releasinglever82, and correspondingly depress the opposite end of the lever 82 so as to withdraw the latch 98 from behind the stop I03, the movement of the lever 82 being great enough to insure complete withdrawal of the latch 98 from the stop I03 without failure. The latch 98 being withdrawn from the stop I03, the slide 90 is free to be retracted in a right hand direction by its spring 93, and pulls the pawl I4 down so as to engage the boss I3 with the periphery of the disc I0. Referring to the location of the lateral finger 8| and the adjacent end of the latch releasing lever 82, Figures 8 and 10, it is evident that the boss I3 will be brought into engagement with the periphery of the primary locking disc I0 before this disc has made. much more: than a quarter turn; Thus, the boss. 13 will ride; on; the periphery/of the. disc 5:0 until it falls into the notch 12. The notches: 111- and 12 have one. edge. beveled: while the other'is straight and radial. The bevel. feeds the dog I3 part way into one side of. the slots then. constitutes an'abutment for the dog even before the dog actually falls. into the slot. This arrangement insures against. fraudulent operation by a quick turn of the. operating knob54 in, an. endeavor to'causethe boss to skip overthe notch, and thereby, expose more thanthe legitimate: onev scoring space.

Simultaneous with the leftv hand movement or cooking of the slide 90, as described above, the dock rod 68; which is attached to the lever III, is likewise moved in the same direction so that its. left hand extremity enters the radial" slot. 65.

or 62'! of the secondary locking device 65. While; in th e radial slot itlocks'the operating: knob; 514: against turning. The lock rod. 68 will be with.- drawn, and consequently the lock released, only when. the coin slide. H9 is. withdrawn. so. as-to permit the. lever II I to be retracted by its spring 5 and thereby withdraw the rod 68'. Thezimportance of this secondary locking mechanism. will be seenin the following example:

Suppose the operator inserted coins and pushed in the coin'slide. H9 just far enough to move slide 90 to a position whereby it had raised boss Itv of pawl I4 just clear of the notch TI, and yet not quite far enough to cause the latch 98' to arise behind the stop I I13. As shownin Figure 10, the

cause the boss 13- to becleared of the notch H in the normal operation of the mechanism. Itv would not be desirable to have the activity of. pawl 14 and latch 98 soclosely timed that the instant the pawl frees the disc ID the latch would catch behind the stop I-Il3-. It would be almost impossible to have such a coordination and have efiiciency. Therefore; it is desirable to have the boss I3 withdrawn; from the notch H, followed by the arising of the latch 98;, behind the stop I03. The result of such a circumstance would be that the latch 98 would not be brought into play with the result that the normal operation of the mechanism wouldbe'disrupted and the operating knob 54 would be free to be turned as much as desired, just as longas the'operator held thecoin slide HS in this position. But, with the engagement: of, the secondary locking me hanism; such a fraudulent operation is not. possible because not until the coin slide I I9 is released by the operator, with the consequentretraction of lever III and withdrawal of lock rod 68 from. the radial slot BLjis the. operating knob 54 free to be turned. Thus, this can be accomplished only when the. slide 911 is fully cooked and the normal operation of the. mechanism assured...

, The'scoreboard casing 5 has on, the middle of its backa bracket I25. which. has a cylindrical portion I-26= which hasav serrated face. I21, with whichis adapted to engage aserrated face, I28. on a similarly formed projection I29 on, the upper end of the standard I30, and a wing nut, equipped bolt I3I traversesthe portion I26 and. the-portion I29, wherebythe angle of. the-casing 5 with respect to the standard I30 may be ad. justed on the axis of the boltv I3-I and locked in position, whereby. the. casing 5 is rigidly supported in the desired angulatedposition. The lowerend of the standard I-30-is cylindrical. as indicated by the numeral I32 and disposed in a socket. I33

pawl 14 is raised higher than just enough to a. foot; operated; lever: I:3;9 for: withdrawing-the; lug; I36; into and out: of engagement. with: the selected: one: of: the depressions I410; which are cirecumferentially spaced on the. part I32 of? the.

standard I:3;0., thisarrangement; being provided to; enable rotating the: standard tov a; desired position of adjustment and locking: the same therein.v

The slide; plate. I34; has runners: I4 Ij adjacent. its; opposite; edges: which slide upon the top of" the base, III-Z which has. retaining flanges: I43 and 5 It4r4r. Locking: means M5 similar in principle to the locking. means already described is. operated by a foot pedal I46. The;first.described lockingfi means being: operated by a foot pedal I41, both foot pedals projecting through a canopy I48 which. surrounds the. standard and covers the mechanism and the slide plate as shown inFigures 11 and 13. of the drawings, whereby the scoreboard maybe adjusted longitudinally or transversely of the base I42 and locked in the selected position.
